FlRE-PROOF-TILE FURRING.

SPECIFICATION forming part of Letters Patent No. 257,366, dated May 2,1862,

Application filed October 29. 1880.

To an whom it may concern:

Be it known thatwe, GEORGE M. MOULTON and Eenns'r V. J oHNsoN, of thecity of Ohicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in the Manufacture andConstruction of Fire- Proof-l urring Tiles; and we do hereby declarethat the followingis a full, clear, and exact description thereof,reference being had to the accompanying drawings, which make a part ofthis Specification.

Our improvements relate, first, to the manufacture of a tire-proof tilefor the purpose of furring for outside walls, vaults, or other parts ofbuildings, where freedom from dampness and its deleterious effects isrequired; second, to the manner of laying the tile in place, whereby acontinuous airspace is obtained over the whole of the furred surface,and also to the method of securing the tile by means of nails andmortar, as herein described.

Our invention consists in the form and application of the furring-tilesfor the purpose required.

\Ve propose to use baked tire-clay for making the tiles, but are awarethat any non-conducting material suitable to be made in this formsuch ascement composition, porous terracotta, plaster-of-paris, and variousother materials-could be used for the purpose. In making thefurring-tiles of baked clay they are made in pairs, in ahollow form, andare thus run through the die, dried, and put into the kiln for burning;but when they are delivered at their place of use they are split apartthrough a groove at each end, which allows them to hold their shapeduring the process of manufacture, but which yields readily to the tapof a masons trowel when applied. to separate them. The tile when made ofclay or other suitable material, may be readily cast in molds or shapedby hand, but we prefer the manufacture described as producing the bestresults for the least money.

In the accompanying drawings, Figure I is an isometrical view of a brickwall furred with tile furring. Fig. II is a horizontal section throughthe furring, showing method of application.

Like letters refer to like parts in both of the figures.

(No model.)

A is a brick wall, which we represent furred on its insideface with thefireproof-tile furring B. Each separate tile 1) is made to project fromthe wall, as shown, thus leaving the air-spaces d. This projection canbe made more or less at will by manufacturing the tile with the endf to.the depth required. Each tile is laid to break joint on every alternatecourse, thus pieces 71., as shown.

The principal purpose for which we have designed this furring-tile isfor use in the construction of substantial buildings, where it is foundnecessary by reason of the porosity of brick walls to use some formot'material that will project from the interior face of the wall, thusleaving an air-space, and at the same time present a suitable surface onthe other side to receive the plaster coat and finish. The usual planfor accomplishing this'result has been to tack strips to the brick wallforming the re quircd projection, and then nail wood or iron laths tothe same, or, as is occasionally done, to build the main walls ofsufficient thickness to allow them to be builtwith a small airspace inthe center, called cavity walls.

The objections to the foregoing methods are numerous; but the followingreasons will be sufficient to explain the necessity fora radicalchangein this system of furring for buildings. When wooden laths aresecured to the strips mentioned the effect, when plastered, is to produce a surface that is easily distinguished from the remaining sides ofa room by the dark discolorations of the laths and strips showingthrough the plaster. This is caused by the moisture coming through thewalls and being absorbed by the wood, thus dampening the plastersufficient to accumulate dust and present an unclean and irregularappearance. This fact is equally true of iron lath, the moistare causingit to rust and discolor the plaster,

and in addition the changes in temperature subjects the iron form oflath to the damaging effects of expansion and contraction, causing theplaster coat to be cracked and unsightly. The objection and consequentunpopularityot' the cavity form of wall is the additional weight, space,and material required byits use, rendering it too expensive for thepurpose. 'By the use of the fireproof-tilefurring all these defectivefeatures are obviated, while at the same time a substantial, economical,non-decaying, andfire-proof material is obtained with all the advantagesbut none of the defects of the numerous forms of furrim at present inuse.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

The combination of the furring-tiles I), made in the shape shown,applied to a brick or other form ofwall,with the nails 0, and formingtheairspaces d, whereby a continuous circulation of air is'allowcd overthe whole of the furred surface, thus avoiding dampness and affordingmeans for ventilation, all as substantially set forth and described.
